Cisco discloses IOS FTP Server flaws

Cisco revealed multiple vulnerabilities in its IOS FTP server this week.

The flaws can result in DoS attacks or malicious users gaining unauthorized privileges.

Cisco products running IOS and configured for FTP server functionality are affected by the flaw, according to a company security advisory released Wednesday.

Successful exploitation can allow remote users access to the IOS device’s filesystem, which can lead to DoS attacks, according to Cisco, which advised network administrators to disable the FTP server feature as a workaround.

The vulnerabilities exist in IOS versions 11 and 12, according to Cisco.

A Cisco representative could not immediately be reached for comment today.
